Crazyhorse 47 Posted September 7, 2018 Share Posted September 7, 2018 Due to the pin on normal shackles catching the bow roller, I went with a galv flathead screw in type but they are Chinese (Burnsco) and of course no stress testing. Whilst its held for a year now, I would prefer something that has a SWL limit for peace of mind. I been told S/S is stronger, more tensile strenght than galv but no idea what weight loading they can take? Unfortunately the only stress certified shackles I can find have a pin that sticks out the side. Quote Link to post Share on other sites
vic008 17 Posted September 7, 2018 Share Posted September 7, 2018 Can you not hacksaw the protruding bit off. Yachting Monthly found galv slightly stronger and less brittle than SS. Sorry that was chain they spoke of. Galv tested shackles had the highest strength but variable results."ss shackles proved to be consistently stronger than equivalent galv steel ones" So doesn't look like much difference Quote Link to post Share on other sites
vic008 17 Posted September 7, 2018 Share Posted September 7, 2018 Further; they had a 10mm tested (rated to 0.5 t) galv d shackle bust at 7.35t ---down to an unmarked galv d- shackle 10mm bust at 3.25t. Quote Link to post Share on other sites
twisty 176 Posted September 7, 2018 Share Posted September 7, 2018 Ask John B about chinese shackles. Once he's finished frothing at the mouth he might give you the lowdown ! Quote Link to post Share on other sites
Crazyhorse 47 Posted September 7, 2018 Author Share Posted September 7, 2018 In around 6-8 weeks there will be countersunk SS shackles that have reliable ratings in NZ. They are leaving the EU this week. Great!! Where? Quote Link to post Share on other sites

KM, on your anchor line you couldn't mouse a shackle like that, or is there some means whereby you can? Quote Link to post Share on other sites

Steve Pope 243 Posted September 9, 2018 Share Posted September 9, 2018 I locktite all my shackles, never had one come loose. Quote Link to post Share on other sites
Steve Pope 243 Posted September 9, 2018 Share Posted September 9, 2018 KM's "correct" anchor shackles have a split pin, just make sure to use a stainless one. Quote Link to post Share on other sites
Steve Pope 243 Posted September 9, 2018 Share Posted September 9, 2018 Split pin that is.!!!!!! Quote Link to post Share on other sites
Crazyhorse 47 Posted September 10, 2018 Author Share Posted September 10, 2018 Our resident guru said get a bow shackle, green pin and do what Knott_him said, center punch the pin. Seems to think they go through the roller a lot easier. Our bow roller is 1966 and still narrow. Quote Link to post Share on other sites
